READING-GLASS;

SPECIFICATION forming part of Letters Patent No. 439,514, dated October 28, 1890.

Application filed April 2, 1890. Serial No. 46,260. (In model.) I

To all whom it may concern.-

Be it knownthat I, ORISON HUFF, of Boston, in the county of Suflfolk, State of Massachusetts, have invented certain new nd useful Improvements in Reading-G1 ses, of which the following is a description snfficiently full, clear, and exact to enable any person skilled in the art or science to which said invention appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which-- Figure 1 is aplan view of my improved reading-glass; Fig. 2, a sectional elevation showing the frame or band connected by the screw-stud; Fig. 3, a perspective view of the stud detached; Fig. 4, views illustrating the ordinary method of securing the frame; Fig. 5, a sectional view showing the handle in position on the stud, and Fig. 6 an elevation illustrating details.

Like letters and figures of reference indicate corresponding parts in the different figures of the drawings.

My invention relates especially to means for attaching the screw-stud to readingglass frames or bands; and it consists in certain novel features, hereinafter fully set forth and claimed, the object being to produce a simpler, cheaper, and more efiective device of this character than is now in ordinary use.

The nature and operation of the improvement will be readily understood by all conversant with such matters from the following explanation In the drawings, A represents the glass, B the handle, and C the band or frame. The band consists of a strip of metal bent to fit the edge of the magnifying-glass A. I After being so fitted the ordinary method of securing the ends of the band is by means of a metallic strip 1), (shown in Figs. 4 and 5,) which is brazed or soldered to said strip. A screw-stud d (see Fig. 4) is then soldered to the strip b, and said strip and screw are cut or divided vertically at the junction of the ends of the frame C, as shown at f in Fig. 5. A handle B is tapped and threaded at g to receive the stud d, whereby said stud-sections are se- The frame being fitted to clamp closely onto the edge of the magnifying-glass when the stud is screwed into the handle B, considerable strain is-exerted on the metallic strip 1). This frequently becomes detached from the frame, as shown at h in Fig. 6, rendering it necessary to resolder the strip onto the frame. 'llhe frame, moreover, is liable to become bent and the'glass cracked or chipped during the operation. I V

In my improvement the stud m is punched or died in a flat metallic blank 1), (see Fig. 3,)

the edges of the blank forming the stud being thereby ineontact at q. Lips 'r are at the same time formed on the body of the blank and turned downward at right angles thereto. The stud m is then oxteriorly screwthreaded and the blank and stud cut entirely apart on the-line q, as shown in Fig. 1. Each section thereof is secured to an end of the frame-band b by the lips 0', which pass through suitable openings formed in the ends of said band and are riveted on the under side thereof at either side of the glass groove, as shown in Figs. 1 and 2. onto the stud m thus constructed, draws its sections closely together and securely clamps the glass in the frame. By this method of construction the stud-sections are fixed firmly on the frame-band, and are little liable to be accidentally separated therefrom, the riveted lips r fastening them tightly on said band. Moreover, the studs thus constructed can be manufactured much more cheaply than when formed in the ordinary manner, less metal being employed to make them and less labor necessary to cut or saw them into sections.

Instead of punching ordieing from a flat blank, as described, the sections may be. formed separately, and ,each portion of thestrips b constructed with lips rthereon. This method, while obviating the necessity of sawing the stud into sections, I consider less desirable, as it is diflicnlt to cut the thread evenly on said sections when formed separately.

Instead of providing the body of the blank with attaching-lips, they may be omitted and The handle B being turned cured together and the glass held in the'frame. 5o

the section-bodiessecured to the frame-band by rivets passing therethrough and headed at both ends in the ordinary manner.

Having thus explained my invention, what 5- I claim is 1. In a magnifying hand-glass provided with a metallic frame-band, a screw-stud punched or died from a metallic blank and provided with lipsfor riveting it to the ends 1 of said band, said stud being divided into sections, substantially as described. V

2. In a magnifying hand-glass provided with a metallic frame-band, a screw-stud punched or died fron; a metallic blank and 15 divided into sections, substantially as de scribed, the supporting-plates of said sections being respectively adapted tobe riveted to the ends of said bands. v

3.111 a reading-glass, the blank 10, punched or died and threaded to form the stud m and 20 provided with the attaching-lip r, substan- I tially as and for the purpose set forth.

4. In a reading-glass, the frame-band C, in combination with the threaded stud m, formed in the blank 1, and provided with lips 'r for 25 attaching it to said band, substantially 'as described. v
